Possibly you developed the irritant reaction because of Retin A
If it had been with hydroquinone
, you would have developed the reaction with depiwhite also as it also contains hydroquinone.
If Depiwhite cream does not cause any problem, you can use it.
Strict avoidance of sun-exposure must be there.
I do not know the exact composition of melanex trio, but I have a strong belief that it also contains tretinoin. Just give a look to its contents and avoid it if tretinoin is one of its ingredients.
Its always better to take medication under doctor`s supervision, so whenever you get time, visit a dermatologist
